At the same time, oxygen is also an important substance required for various reactions in the earth's ecological environment. In biological laboratories, oxygen generation and supply equipment are usually needed to provide the necessary breathing environment for various biological experiments. The oxygen generation and supply devices used in existing biosafety laboratories can basically meet people's use needs, but there are still certain shortcomings. First, the compressors in the oxygen generation and supply devices used in existing biosafety laboratories are mostly fixedly installed inside the device. The vibration generated by the compressor during actual use will cause the connection inside the device to loosen, affecting the working stability of the device. At the same time, the noise generated by the vibration will affect the physical and mental health of the experimenters; second, the heat dissipation of the existing oxygen generation and supply devices is mainly carried out by air cooling and heat dissipation fans, but the existing air cooling and heat dissipation structures are mostly fixedly installed on the device, and it is difficult to adjust the position of the heat dissipation fan during use, thereby affecting the heat dissipation performance of the device and shortening the service life of the equipment; third, the oxygen generation and supply devices used in existing biosafety laboratories need to manually place and install the oxygen storage tube at the filling position when filling oxygen, which increases the labor intensity of oxygen filling and reduces the practicality of the equipment.
